HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 670,437, dated March 26, 1901.

Application filed June 26, 1900. Serial No. 21,665. (No model.)

To ctZZ whom it may concern:

Be it known that I, SOLOMON SOHWARZ- sCHILD, a citizen of the United States, residing at Rochester, New York, have invented certain Improvements in Heating Apparatus, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to certain improvements in heating apparatus, designed more particularly for use in connection with stoves heated by gas, but applicable also to oil or gasolene stoves.

My improvements are fully described and illustrated in the following specification and the accompanying drawings, the novel features thereof being specified in the claims annexed to the said specification.

In the accompanying drawings, represent ing my improvementsin heating apparatus, Figure 1 is a perspective view. Fig. 2 is a section on the line 2 2, Fig. 1. Fig. 3 is a partial plan view. Fig. 4 represents the escapeopening.

A represents the body or casing of any suitable gas, oil, or gasolene stove to which it is desired to apply my improvements. ,The stove may be provided with a plurality of burners of any ordinary or preferred construction. The upper plate B of the stove A is provided with one or more orifices O, the number and location of such orifices dependin g upon the number of burners employed.

D is a'perforated cover placed above the upper plate B and provided with flanges E all around, whereby a recess or heating-chamber F, Fig. 2, is formed below the top and between it and the perforated upper plate B of the stove. The top is provided with a plurality of lid-openings G, corresponding in number and arrangement with the openings 0 in the upper plate B.

H represents removable lids adapted to close the openings G. The lids H are perforated, preferably near one edge, as indicated at 1, these perforations being also adapted for lifting the lids by means of the Ordinary stove-lifter. The cover is provided with escape-orifices J of any suitable shape and adapted to be closed by the register or other Valves K. In the construction shown these ing on the cover.

valves K are recessed into the upper side of the top, so that its whole upper surface is flat. For the admission of air into the inside of the casing A suitable perforations L may be employed.

In the practical use of my improvements the burner or burners may be lighted within the casing, and the desired culinary operations may be performed on the cover with or without the removal of one or more of the lids H. The

'heatiug-chamber formed above the stove by the recess in the lower side of the cover D secures perfect combustion and a material economy in fuel. Where a numberof escapeopenings are employed, those nearest the ignition burner or burners may be closed by the valves K, while those at a distance may be opened, so as to secure passage of the heat laterally through the heating-chain ber,whereby a single burner may be employed to effectively heat the whole cover.

The location of the orifice I in the lid H near one edge permits the escape of the heat-.

ed gases at one side of a culinary vessel rest- The cover. being open at the bottom, with the edgesof the flanges thereof resting on the upper plate of the'stove, the lateral circulation of the heated gases is promoted by their escape through the lidopenings in the cover, which occurs whether the other openings are open or closed; but the best results'are secured by the use of one or more of the registers, by which the heat is strongly defi ected to parts of the cover at one side of the burner;

' My improvement is cheap and durable, be-

ing readily made of iron and of such shape and dimensions that it may be applied to any of the different styles of stoves now in use.

It may be ornamented or finished, as by nickeling, in any suitable or preferred manner.

I claim- 1. The combination of a stove having a plurality of burners with a removable cover provided with a plurality of lid-openings and means for directing the products Of-combustion from any of said burners through or by any of said lid-openings, substantially as described.

2. The combination of a stove having a plurality of burners with a removable cover there- IOo ings having lids for closing them and with a plurality of dam pered o u tlet-openi ngs, whereby the products of combustion from a single source of heat may be directed to different portions of the removable cover, substantially as described.
